The Chinese government reported the world’s first possible human case of the H10N3 strain of bird flu.

According to reports a 41-year-old man in Jiangsu province, which is northwest of Shanghai, has contracted the flu on May 28. The National Health Commission said the man was hospitalized on April 28 and is in stable condition, the Associated Press reported.

There have not been any reports of another human case of H10N3 anywhere else in the world, the AP reported.

Reports did not say how he became infected.

According to the AP, the health agency said the infection was possibly due to an “accidental cross-species transmission” and the “risk of large-scale transmission is low.”
